There are several parts of a stepper motor, for example, a permanent magnet rotating shaft, called the rotor, and electromagnets on the stationary portion that surrounds the motor, called the stator. One complete rotation of a stepper motor. We can see that the rotor is beginning at the upper electromagnet, which is currently active (has voltage applied to it). To move the rotor clockwise (CW), the upper electromagnet is deactivated and the right electromagnet is activated, causing the rotor to move 90 degrees CW, aligning itself with the active magnet. This process is repeated in the same manner at the south and west electromagnets until we once again reach the starting position.
As many people find it difficult to cope with stepper motors and other motors at the same time, some people begin to take an active part in taking care of their stepper motors. Stepper motors are electromagnetic actuators that convert input pulses to output motion. They are different from ordinary direct current (DC) motors in that, when energized by a voltage or current pulse train, the step motor moves an incremental amount for each pulse it reads.Stepper motors are commonly used in computer peripheral equipment such as printers, tape drives, and disk drives. Additionally, they are used in machine tool controls, process control systems, robots, and other industrial applications.
